Cause
This is most probably caused by the listener and database not being started yet when the EM agent is started which picks up a wrong character set.
You can check that the issue is happening from the EM agent from trace files, e.g. emagent.trc showing:
PLS-00553: character set name is not recognized

Solution

Restart the EM agent to fix the issue

$emctl stop agent

$emctl start agent

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.
